Catalytic device with internal heat exchange

Method for treatment of a fluid quantity including chemical reacting means such as combustible materials above a certain minimum quantity in a catalytic device, said method comprising:

• entering said fluid quantity into the catalytic device through an inlet;
• directing said fluid quantity through at least three mutually connected passage sections of said catalytic device in which said at least three passage sections include a main reaction passage section heat exchanging in counterflow with a main heat transfer passage section, wherein at least one section includes catalytic material of one or more kinds in which the catalytic material reacts with and/or enhances the reactions of said combustible materials, and wherein at least one of said at least three passage sections comprises a plurality of substantially parallel pipes;
• heating or cooling said fluid quantity in said at least three passage sections by said internal heat exchange in said catalytic device between said sections;
• and
• emitting the treated fluid quantity from the catalytic device through an outlet.

Catalytic device for treatment of a fluid quantity including chemical reacting means such as combustible materials above a certain minimum quantity, said device comprising:

• a container including at least one inlet and outlet for said fluid quantity;
• said container further comprises at least three passage sections being mutually connected, where at least one section of said passage sections includes catalytic material of one or more kinds;
• wherein the positioning of said passage sections forms at least one internal heat exchanger with mutual heat exchange between the sections;
• wherein the at least three passage sections include a main reaction passage section which heat exchanges in counterflow with a main heat transfer passage section of said at least three passage sections;
• and
• wherein at least one of said at least three passage sections comprises a plurality of substantially parallel pipes.
